SCRAPER-OPERATING APPARATUS.

SPECIFICATION forming part of Letters Patent No. 543,832, dated July 23, 1895.

Application filed August 11, 1894. Serial No. 520,065. (No model.)

To a/ZZ whom it may concern:

Beit known that I, HENRY G. BUTLER, a citizen of the United States, residing at Kenosha, in the county of Kenosha and State of Wisconsin, have inventeda new and useful Improvement in Scraper Operating Apparatus, of whichthe following is a specification.

My invention relates to an improvement in the class of apparatus involving cable-winding mechanism for operating a scraper, dredgeor other form of conveying means, such as would be employed in railroad-grade Aand levee construction, dredging, excavating for foundations and sewers, for feeding clay to the lire in burning clay to make ballast, and in stonequarries, coal-mines, and the like; and it relates, more definitely stated,to

an improvement in the class of such mechanism in which the winding mechanism involves wlndmg-drums supported on a preferably locomotive-base, such as a car or boat, and

driven by a suitable engine and controllable to produce the three filling, hoisting, and conveying operations of the scraper.

My improved apparatus is advantageously applicable to any of the uses referred to; but for .the sake of convenience and to avoid prolixity I confine the description hereinafter contained mainly to the use thereof in connection with ballast-burning, and illustrate it in the form best adapted thereto in the accompanying drawing, which shows my improvement by a view diagrammatic in its nature-and as operating upon a ballast-burning fire.

A is the -support for my improved mechanism, indicated as a car movable on a track t, which may be considered, for the purpose of the further description, to extend alonga pile of burning clay or ballast-burningiire B, toward which a boom may extend as usual from the support, though I may also employ, in-

v stead of a boom, atower (indicated at C) at the vside of the fire opposite that at which the car A is provided, and which, like the latter, is on a car C movable upon a track t' extending lengthwise along the sideY of the pile B.

At A', .I indicate a mast on the car A as a medium for supporting the guide-pulleys for cables, as hereinafter described, and the car A also carries the winding mechanism comprising drums D, E, and F. These drums should,

as is usual in apparatus of the class to which my improvement relates, be driven by suitpower.) A cable r is fastened at one end to the drum E, proceedsl thence upward over a guide-pulley r', journaled on the upper end of the mast A', to the tower C, (corresponding to the outer end of the boom hereinbefore referred to,) at which its opposite end is fastened, and on the cable r a scraper G is suspended at its bail q, the scraper shown being of the variety open at one end where it is adapted to scrape by cutting and plowing the soil, and having a bottom q hinged near the open end of the scraper to dump the contents by swinging downward and being held in closed position by a catch qz controlled to release it through the medium of a rope o passing over a guide-pulley o on the mast to the car 5A, where it is accessible for manipulation, and whence it is adapted to pay out withthe outward travel of the conveyer or scraper G, as hereinafter described.

A cablep fastened at one end to the drum D proceeds thence over a guidepulley p journaled on the top 'of the mast (and which may, if desired, be loose on the same shaft with the guide-pulley r) about a pulley p2 on the upper end of the tower C (which corresponds with the outer end of the aforesaid boom) from which it extends and is fastened at its opposite end to the yoke qi extending rearward on the scraper.

From the forward drag-bar of the scraper it is connected by a cable n withthe windingdrum F.

The operation is as follows: Supposing the scraper G to be down ou the ground in position to be dragged toward the car A to iill, by turning the drum-F to wind the cable r1, upon it, and at the same time allowing the cablep -to pay out or unwind from the drum D, the

l'OO

carried outward by the cable p to the re B,

upon which, when reaching a desired position with relation thereto, the contents of the scraper aredumped by tugging the rope n to release the catch q2 and permit the bottom q to drop on its hinge. Thereupon the drums D and E are stopped and permitted to be reversed to allow their cables to pay out for lowering the scraper to the ground again, turning of the drum F to wind up its cable n meantime producing the return of the scraper to the incline in the ground toward the car, up which it is dragged to refill while the cable p still pays out, though the drum E may then be stopped from permitting further paying out of the cable r. Thereupon. the hoisting, carrying, and dumping operations of the scraper are repeated, as described.

I have indicated by dotted lines in the drawing how the drum D may be located on the car C', thus behind the scraper and connected with the latter by the cable fp, which would be practically the saine as providing the drum D on the car A and passing the cable about the pulleys p and p2 to the scraper, accord-V ing to the full-line representation on the draw? ing.

By providing the supports A and C in the form of cars on tracks they may be readily moved from place to place with relation to the fire B for filling and dumping the scraper at desired points thereon.

What I ciaim as new,and desire to secure by Letters Patent, is-

In an apparatus of the nature set forth,the

combination of winding-drums D, E and Fon a movable support A carryinga mast A', a tower C on a movable support C distantly located from the support A guide-pulleys 19' HENRY G. BUTLER.
